It will be the first time Ake has faced his old club since being sold this summer.
He told the London Evening Standard: “I am not intimidated by anyone.
“I obviously have respect for my opponents and it will be a good battle, for sure.
“I always want to test myself against the best players, so I’m actually looking forward to it. I won’t go into it soft.
“He is a top striker and has been playing really well so far. He has got all the attributes. I need to be focused and I hope to stop him.
“Playing against Chelsea won’t give me more motivation. I have nothing against them. It is not like I will be going out there thinking, ‘I want to prove this and that’. But to win will be the ideal story and we fancy our chances.”
